ABQ010 – Abaqus:

Temperature-dependent linear visco-hyperelastic model

with stress softening

Description

This Test Program is recommended for modeling the temperature effects of rubbers and other polymers that exhibit the same relaxation behavior over a wide range of deformation, accompanied by stress softening, also known as Mullins effect.

Veryst will provide a calibrated material model (either a built-in Abaqus or PolyUMod model) for the observed response and the material.

The resulting set of parameters can be used directly in Abaqus CAE or the input file.

Specimen Requirements

25 tensile (dog-bone) specimens

10 planar tension specimens

10 compression cylinder specimens

25 volumetric compression specimens

See description of individual tests for details on specimen geometries. Note that we request extra specimens to ensure a sufficient supply of specimens for valid testing.

Veryst can also assist in molding standard and non-standard test specimens. Please contact usif you are interested in discussing this option.

Additional Validation

Veryst can perform additional validation, depending on the target material and the simulation application, through any of the following tests and any necessary component level FE simulation:

Impact testing

Micro-to-macro indentation responses

Compression relaxation tests

Cyclic tests with loading/unloading between different strain levels and zero stress level at different rates
